Transformation of Bessel beams passing through uniaxial y-cut crystal

摘要

We investigate a propagation of the zero-order Bessel beam through an uniaxial crystal along the direction perpendicular to the crystal axis. Astigmatic-like transformation of beam transverse distribution is shown with simulation based on plane-wave expansion. The simulation is verified by experimental study of Bessel beam passing through y-cut LiNbO crystal.
